After using his Hydrification Technique to merge with a water source, Suigetsu can form a giant wave that looks like a demon-like fish. Suigetsu can use this form to battle larger opponents, or he can use it to shield allies from attack. Though it was strong enough to push back an Eight-TailedKiller B, it was not strong enough to withstand a Tailed Beast Ball, which rendered Suigetsu unconscious, falling into a jelly-like state.
